Rohini Satellite (RS-1)Series

First RS-1

Objectives :
The satelite provided data on the fourth stage performance and ranging.

Second RS-1

Launch Date : May 30, 1981

Weight : 35 kg

Lauched by : India, SLV-3 (D-1) rocket

Orbit : 300 km x 900 km elliptical orbit (97 minutes period)

Objectives : Carried a Land Mark sensor payload whose solid state camera performed to specifications. The satellite re-entered the earth's atmosphere nine days after lauch on account of the launch vehicle's injecting the satellite into a lower than expected altitude.

Third RS-1

Launch Date : April 17, 1983

Weight : 35 kg

Lauched by : India, SLV-3 (D-2)rocket

Orbit : 300 km x 900 km elliptical orbit (97 minutes period)

Objectives : The Smart Sensor Camera was the primary payload on board
the satellite. It was operated for over five months and sent more than 2500
pictures frames in both visible and infrared bands for identification of
landmarks and altitude and orbit refinement. The camera had on-board processing
capability to use the data for classifying ground features like water,
vegetation, bare land, clouds and snow. After completing all its mission goals,
RS-D2 was closed down on Sept. 24, 1984.
